If ACTION-IF-FOUND is not specified, the default action -# will define HAVE_PTHREAD. -# -# Please let the authors know if this macro fails on any platform, or if -# you have any other suggestions or comments. This macro was based on work -# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help -# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by -# Alejandro Forero Cuervo to the autoconf macro repository.
